Routing audio maschine<->traktor with jack in windows 7

Hi all,
i have just setup the audio communication between maschine and traktor, and set maschine as a slave, and traktor as the master. So the timestretch function is now possible "in" maschine, treated in traktor, and put in a maschine dedicated tracks.

I don't know if you are concerned, but in windows, without a dedicated external audio hardware, the only solution was jack as an equivalent as mac's soundflower ...

Click on "connect" button, the connect map appears with only the system icon.

Click on "Disconnect All" to reset all the pre-conf

Start Maschine and wait 15s, the Maschine icon appears in the map box

Expand Maschine in the left col of the box, expand System in the right col of the box.
- Drag and drop Maschine out 1 L on playback_1 (or first item in the system's input audio port)
- Drag and drop Maschine out 1 R on playback_2 (or second item in the system's input audio port)
Collapse the maschine list in the left col

Start Traktor and wait that the traktor icon appears in jack connect's box

Expand Traktor in the left col of the box, expand Maschine in the right col of the box.
- Drag and drop Traktor out 1 on Maschine In 1 L
- Drag and drop Traktor out 2 on Maschine In 1 R
- Drag and drop Traktor out 3 on Maschine In 2 L
- Drag and drop Traktor out 4 on Maschine In 2 R

Close this map-box

Create in Maschine an intrument with "input" in first tab and select "Ext in 1"
for decks A and B input

Create in Maschine another intrument with "input" in first tab select "Ext in 2"
for decks C and D

Maschine is start in traktor / click on metronome / play-pause in "send" Transport Area

NB:
Don't edit preferences from Maschine/Traktor if jack-control windows is started, just if jack port audio only is started
You can use patch bay in jack-control windows to automating the connection
Always launch jack port audio, then jack-control, then maschine then traktor
If a prob appears with sound, or maschine/traktor, you must all close, and all relaunch

I know this is kind of old but i still have a little trouble doing this. no mini jack administration windows appeared during the last steps. i dont understand the part where you Click on "connect" button, the connect map appears with only the system icon. Any kind of help would be greatly aprecciated

This has worked great for me until I upgraded from Traktor 2.7 to Traktor 2.10 and beyond. I have tried to uninstall and reinstall all pieces and followed the Jack install instructions to a T. I can only get Jack to work with 2.7. The other versions close Traktor upon selecting Jack audio; with error that states - "Traktor 2 has stopped working -- A problem caused the program to stop working correctly. Please close the program." If anyone has any information on why this is the case, PLEASE respond!
